The graphite form in cast iron is the structure parameter deciding on its all physical and mechanical properties. Three basic forms of graphite: flake, vermicular (compact) and nodular (spheroidal) are singled out in standard cast iron grades, without a heat treatment. Standards of individual grades of cast iron the most often allow only the homogeneous graphite form, sometimes with addition of 5÷10% of the other form. The interesting and - in the authors opinion - future-oriented material can constitute cast iron in which various forms of graphite are present, e.g. in comparative amounts: spherical and vermicular cast irons. Cast iron within which graphite occurs in two or three forms was named „Vari-Morph” (VM) cast iron, i.e. the one in which spherical and vermicular or vermicular and flake graphite occur in a wide range of proportions. The results of investigations of these new cast iron grades and their properties are presented in the hereby paper.
